FAUCET OR TAT FOR WATER PIPES, ETC.

Application led August 29, 1923. Serial N`o. 660,001.I

To all whom t may concern.'

Be it known that I, O'rro SCHOTT, a citizen of the German Republic,residing at Stuttgart, lVurttcmberg, Germany, have invented certain newand useful Improvements in Faucets or Taps for Water Pipes, Etc., ofwhich the following is a specification.

The invention has to do with a faucet of an already known outwardconstruction that permits the removal of a regulating nozzle withoutshutting off the water supply elsewhere in order to replace a washer.This is made possible by a valve in the faucet itself, that turns oifthe water automatically.

The already known faucets have various disadvantages, for instance: Uponopening the faucet, the water not only flows through the proper outletbut also spurts through the threads that connect the nozzle with themain part of the faucet, and in that way wets the person using thefaucet. This present invention contains a new form of valve thatremedies the above disadvantage, all the waterl owing downwards throughthe proper outlet.

Another improvement this faucet offers is the simplicity of theautomatic valve, that does away with the disadvantages of the known coneor ball valves, which a single grain of sand etc., can cause to leak.

The drawing accompanying this specification-illustrates the working ofthe invention and shows:

. Figure 1, a longitudinal section as seen from the side of the faucetwhen closed,

Figure 2, a longitudinal section on line 2-2 of Figure l, seen from thefront of the faucet when open.

Figure 3, a longitudinal section of the automatic valve when shut.Figure 4, the movable member of the lower valve as seen from the side.

' Figure 5, the movable member of the lower valve as seen from below.

The ordinarily visib-le parts of the faucet consist of the delivery pipea `and the regulating nozzle b, which latter screws over the free end ofthe delivery pipe; this nozzle is provided with several ridges otoinsure a good hold. v

A nipple comprising. a plug e perforated by they hole d is screwed intothe free end of the delivery pipe a, and according to my invention, boththe plug and the hole therein are of aV larger diameter at the bottomthan at the top, producing a bellflange f.

l Above plug e is a cylindrical chamber g', in which the inventionprovides for a freely movable leather, rubber, or the like disk It toopen or close the passage WZ.

The dimensions of chamber g are such; that the water is able to passaround the disk h; that the disk is adapted to shut the passage cZ; thatthe disk can not get out 'of its right position, that is to say, thedisk will always be pressed down upon its proper seat whenever thenozzle is removed as shown in Figure 3.

Between delivery pipe a and regulating nozzle o there is a movable valvepart, the lower end of which rests upon a small fiat shoulder inside ofthe nozzle b and has a shape (for instance, like that of a cross adaptedto allow the water to pass freely between` its extremities.

The general working method of this kind of faucet can be accepted asalready known, which renders unnecessary any further description. Myintention is rather to explain the'advan'tageous results brought forthby the new arrangements in the present improvement.

These advantageous results already appear in the manufacture of thefaucet, almost no work being required to form the upper automatic valve,since the boring that is necessary for the thread of the plug e, needonly beextended a short way to form the chamber g.

By means of the free play allowed to disk it, it is impossible for anyforeign matter to rest upon the edge that supports the disk and impairthe perfect functioning of the valve.

Another improvement that this faucet offers, is that the seat of thewasher Z is situated in the plug e, so that the washer is entirelysurrounded by a ring wall f. In lthis way the water flowing from thevalve does not immediately come' in contact with the inner wall of theregulating nozzle b, as it happens with the already known systems inwhich the water can easily go up through the threads. On the contrary,with the present faucet the water dashes against the wall f, is thusdirected downward and is prevented from passing through the threads andescaping at the upper end of the nozzle. What I claim as new, and forwhat I desire Letters Patent is 1. In a faucet, a discharge pipe, anozzle threaded thereon, asleeve threaded in the lower end of said pipe,a bell flange on'the lower end of said sleeve, a shoulder on the innerWall of said nozzle, a spider loosely supported on the shoulder, apacking member supported on said spider, said packing member arranged toseat in said flange whereby the packing member may be forced to and froman operative position by a rotary movement of said nozzle.

2. In a faucet, an exteriorly threaded discharge pipe, an interiorlythreaded nozzle mounted thereon, a shoulder on the inner wall of saidpipe providing an enlarged bore adjacent the lower end thereof, anexternally threaded nipple mounted in the enlarged portion of said borewith the upper end `thereof in spaced relation to said shoulder,

a flat disk loosely mounted above said nipple, an annular shoulder inthe wall of the bore of said nozzle, a closing member' loosely-mountedon said shoulder and a pin extending upwardly from said closing memberand engaging saiddisk to hold. the same in an open position.

3. In a faucet, a discharge pipe, an offset shoulder in the wall thereofto provide an enlarged bore at theend of the pipe, said pipe beinginternally threaded at the lower end thereof,an exteriorly threadednipple operatively threaded in` said pipe with the" upper endthereof inspaced relation to said shoulder, a disk loosely positioned between saidshoulder and said nipple, an internally 'threaded end of said pipe, theupper end of said nipple being positioned in spaced relation to saidshoulder, a disk loosely positioned between said shoulder and the upperend of said nipple, said disk adapted to seat,

on the upper end of said nipple and clos the bore, therein, said pipe.being exteriorly threaded and an internally threaded nozzle memberoperatively mounted on the lower end of said pipe, an offset shoulder inthe Wall of the bore of said nipple, a spider supported by said offsetshoulder, a pin coaxially fixed to said spider so as to project upwardlytherefrom, a packing washer mounted on said pin and arranged to seatagainst the lower end of said nipple, wl1ereby the nozzle may be rotatedto open and close the lower end of said nipple, the upper end of saidpin positioned against said disk whereby the same is held away from itsseat in said nipple in the operation of said valve.

In testimony whereof I ailix my signature.
